This study, performed primarily by Lucia Vincenzetti, was recently published in the European Journal of Immunology.<\/p>\n

Epigenetic modifications such as DNA methylation are crucial to the appropriate regulation of gene expression in T lymphocytes, ultimately influencing all aspects of T cell biology. This study determined the dynamics of modifications of cytosines in the genomic DNA (5mC and 5hmC), and addressed whether DNA demethylation processes linked to T cell activation occur primarily through active or passive processes.<\/p>\n

The authors found that activation of primary human na\u00efve and memory T lymphocytes led to a global reduction of genomic 5mC and 5hmC, which was crucial for the proper acquisition of T cell effector functions. However, while all T cells relied primarily on proliferation-dependent processes to dilute DNA modifications, na\u00efve T cells appeared to also take advantage of an active component of 5hmC removal.<\/p>\n\n\n\n\n

Activation of primary human na\u00efve and memory T lymphocytes leads to a global reduction of genomic 5mC and 5hmC. While all T cells rely primarily on proliferation-dependent processes to dilute DNA modifications, na\u00efve T cells appear to also take advantage of an active component of 5hmC removal, at least in a window time following activation and preceding the initiation of proliferation.
